Wire rope hoist the spring balancer role analysis
1, Of generally wire rope hoist motor axis is perpendicular to the axis of the reel, the ordinary electric hoist is turbocharged transmissions, compare the size of the width of the area, are somewhat bulky structure, mechanical efficiency is relatively low, the processing is more difficult. Market manufacturers in the production of this structure type product, this product has been excluded from the stage of history.
2, while the motor axis is parallel to the roll axis of the electric hoist, the advantage for the height and the length dimension is small, the electric hoist the disadvantage is the width dimension, packet, and manufacturing and assembly complexity, the orbital turning radius is large.
3,Electric hoist motor mounted inside the drum, the advantage for the length of the small size, compact structure. The main drawback to the motor heat, poor, poor packet, inspection, installation, maintenance Motor inconvenience, complexity of the power supply unit.
4, adjust the the adjustment worm on the balancer, balancer balance weight and the weight of the tool used electric hoist tools travel anywhere to achieve balance, that is, the tool is in a weightless state. Clockwise adjustment, balance weight increases on the contrary reduced when the supplier has to balance the weight of tune in the middle value, the balance weight adjustment can not be higher or lower than rated, otherwise it will affect the normal operation.
